Sea to Summit Pack Tap

What Sea to Summit has done here is simply tart up an old fashioned wine bladder (which many have converted for years of service as water bladders in people's packs) and slap a decent price tag on it

Which is brilliant. There is little to fault in this bladder. It is light, easy to use, durable, very well constructed, well thought out (even to replacing the spigot/tap with an easier to use and more durable silicone version and the stitching/construction is impeccable.

Best thing about a bladder is that it stabilises any water in your pack (as opposed to half full bottles sloshing around), is very light and packs away to nothing when empty (so nothing to carry a couple of extras or an extra large one in the pack for extra water carrying capacity if facing a long dry day on the trail).

This is a thorough refinement/enhancement of the trusty old wine bladder and I recommend it.
